Backend slows down other users' experience

Hi bubblers

I need your help to understand the behaviour of my app. Currently there are a few users using it simultaneously. The issue I’m having is that when one user creates a bunch of things (i.e. sends an order to the backend to create about 50-100 things via an API workflow), the app of the OTHER USERS slows down / freezes. The curious thing is that when the other users restart the app (refresh the page), the app works perfectly, even if the backend hasn’t finished creating the things yet.

I thought that what is running in the backend is completely independent from what the user is seeing in the front. Am I correct?

Note: I’m not using “do a search for’s” anywhere in my app to load the things that are being created
